Direct answer: machine ROI has five inputs – achievable output, selling margin, fixed cost, utilisation ramp and capital cost (est.). Payback is total investment divided by monthly net profit, and the honest version uses a ramp from 25-40% utilisation in month one to 70-85% by month twelve, not full capacity from day one. Most disappointing purchases were calculated on brochure capacity.
The Five Inputs
| Input | How to get it |
|---|---|
| Achievable output | real shop speed, not brochure speed |
| Selling margin | revenue minus consumables, as a percentage |
| Fixed cost | EMI, salary, rent share, power |
| Utilisation ramp | 25-40% month one, 70-85% by month twelve |
| Capital cost | machine plus installation, stock and working capital |
Worked Example (est.)
| Line | Value |
|---|---|
| Machine plus setup | Rs 5,00,000 |
| Realistic output at 70% utilisation | 1,200 sqft per month |
| Average selling rate | Rs 120 per sqft |
| Monthly billing | Rs 1,44,000 |
| Consumables at 40% | Rs 57,600 |
| Gross margin | Rs 86,400 |
| Fixed costs | Rs 45,000 |
| Monthly net | Rs 41,400 |
| Payback | about 12 months at steady state |
Now apply the ramp: if months 1-3 run at 35% utilisation, payback stretches to 15-18 months (est.). That difference is what most buyers miss.
Utilisation Ramp Reality (est.)
| Month | Utilisation | Net vs steady state |
|---|---|---|
| 1-3 | 25-40% | often negative after fixed costs |
| 4-6 | 40-60% | approaching break-even |
| 7-9 | 55-75% | profitable |
| 10-12 | 65-85% | steady state |
Assumptions That Break ROI
- Brochure capacity – real throughput is typically 55-75% of rated speed (est.).
- Full utilisation from day one – demand takes months to build.
- Ignoring the ramp’s cash burn – months 1-3 need reserve funding.
- Zero downtime – budget 3-8% of production hours.
- Ignoring wastage – 5-12% of material disappears in setup and rejects.
- Forgetting working capital – 20-30% of the budget should not be in hardware.
Quick Screening Rules
| Rule | Why |
|---|---|
| EMI under 30% of expected gross margin | survives a slow month |
| Payback under 24 months at 70% utilisation | technology does not get stale before payoff |
| Three months of fixed cost in reserve | funds the ramp |
| Confirmed orders covering 40% of capacity | reduces ramp risk sharply |
| Spares and service engineer identified | downtime is a real ROI input |
Comparing Two Machines Fairly
Compare on cost per finished sqft at realistic utilisation, not on purchase price. A cheaper machine that runs slower and wastes more material often costs more per sqft than a better one (est.). Include consumables, spares, power and downtime, then divide by achievable output – that single number decides most purchases correctly.
Our Verdict
Calculate ROI on realistic utilisation, with a ramp, wastage and downtime included. A machine that pays back under 24 months at 70% utilisation, with orders covering 40% of capacity, is a sound decision; anything calculated on brochure capacity is a hope.
FAQs – Printing Business ROI Calculation Guide
How do I calculate ROI on a printing machine? (est.)
Divide total investment by monthly net profit at realistic utilisation – billing at 70-85% capacity, minus consumables and fixed costs (est.). Include a ramp from 25-40% utilisation in early months, which typically stretches payback by 20-40%.
What payback period is acceptable for a printing machine? (est.)
Under 24 months at 70% utilisation is a practical threshold (est.). Longer paybacks expose you to technology changes and to the risk that demand never reaches the assumed level.
Why do machine ROI calculations fail? (est.)
Because they use brochure capacity instead of real throughput, assume full utilisation from day one, ignore downtime (3-8%), ignore wastage (5-12%) and put the entire budget into hardware with no working capital left (est.).
How much of my budget should be working capital? (est.)
20-30% (est.). Consumables, stock and two months of operating costs decide whether the machine can actually run at the volume the ROI assumes.
What utilisation ramp should I plan for? (est.)
25-40% in months one to three, 40-60% by months four to six, and 65-85% by month twelve (est.). Early months are frequently loss-making after fixed costs, so the reserve matters as much as the machine.
How do I compare two machines fairly?
Compare cost per finished sqft at realistic utilisation, including consumables, spares, power and downtime (est.). Purchase price alone is misleading – a slower machine that wastes more material often costs more per unit of output.
